Do you mean:

F = F_o e^{\omega t}

?

Identities:

log(x*y) = log(x) + log(y)

log(\frac{x}{y}) = log(x) - log(y)

log(x^y) = y*log(x)

Pretty much the same for natural logs.

Try it using the steps I give you.

1. Move Fo to the left so that the exponential is alone.
2. Insert log (or ln) on both sides.
3. Remove the wt as powers by the rule: log\ a^x = x\ log\ a
4. Divide by something to get t alone.

Can you get it? If yes, post what you get. If no, post where you are stuck. :)
